Filed: 1981-12-23
Abstract: PURPOSE:To produce a synthetic resin foam-molded product being excellent in quality, by a method wherein, after a resin foaming sheet is brought into direct contact with a pair of heating plates for heating and softening, a molding is conducted. CONSTITUTION:A synthetic resin foaming sheet 1, wound around a winding roll 2, is unrolled, the sheet is positiond by the nip formed by heating plates 3 in a manner to bring it into direct contact with the plates 3, and it is usually heated to about 100-170 deg.C for softening.
